NOTE
-
In this subclass, the following terms or expressions are used with the meanings indicated :

- "photosensitive" means not only sensitive to electro-
magnetic radiation but also to corpuscular radiation;
- "photosensitive compositions" covers photosensitive
substances, e.g. quinonediazides, and, if applicable,
binders or additives;
- "photosensitive materials" covers the photosensitive
compositions, e.g. photoresists, the bases carrying them
and, if applicable, auxiliary layers.

WARNING

Groups G03F 1/0007-G03F 1/16 are no longer used for the classification of documents as of January 1, 2012. The backfile of these groups is being reclassified into groups G03F 1/20-G03F 1/92 as follows: G03F 1/0007-G03F 1/0092 and G03F 1/08-G03F 1/16 into groups G03F 1/20-G03F 1/86; G03F 1/02 into G03F 1/88; G03F 1/04 into G03F 1/90; G03F 1/06 into G03F 1/92. Until reclassification is complete, groups G03F 1/0007-G03F 1/16 and G03F 1/20-G03F 1/92 should be considered in order to perform a complete search.

NOTE
-

- in this group the term "hybrid" is meant to involve the
combination of plural types of phase-shifting pattern in a
single common pattern; a mere structural, e.g. geometrical,
association of masks with separate patterns is not considered
hybrid;
- hybrid masks combining a binary pattern with a
phase-shifting pattern are only classified in the group
corresponding to the phase-shifting aspect, the binary
pattern being considered a trivial feature in this
context
